VIB RATOR.

Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed November 19, 1906. Serial No, 343.995. Renewed June 22, 1907. Serial No. 380242.

T 0 all whom it may concern:

Be it known that I, AUcUs'r It. LUscHKA, a citizen of Switzerland, and a resident of Chicago, in the county of Cook and State of Illinois, have invented. certain new and useful In'iprovements in Vibrators, of wl'iich the following is a specification.

This invention relates to the vibratory type of current interrupters used in connection with spark coils and the like, and has for its object to provide a simple and ell'icient structural arrangement and combination of parts, adapted to afford an accurate adjustment or variation in the frequency of the interruptions, and in connection therewith to provide a simple and eilective means for maintaining the parts at the required adj ustment, all as will hereinafter more fully appear.

In the accompanying draninga Figure 1, is a side elevation, partly in section of a vibrator embodying the present invention. Fig. 2', is an end elevation of the same. Fig. 3, is a sectional plan on line :ra;, Fig. 1.

Similar numerals of reference indicate like parts .in the dil'l erent VlC-V-SS.

Referring to the drawings, 1 represents the usual end head of a spark coil, or like appliance, upon which the vibrator mechanism is mounted. 2, is the core of said coil arranged to project through said head to form the usual fixed anvil for the vibratory hammer or tongue of the vibrator.

3, is a yoke piece secured to the head 1, and adapted to carry the adjusting screw 4, which constitutes the usual adjustable anvil of the vibrator.

5, is the vibratory hammer or tongue ar ranged to vibrate between the anvils aforesaid; in the present invention sai iammer consists of a flat plate of metal provided at one end with pivot ears 6, by which it has pivotal connection with its pivot bracket 7, attached to the head 1, as shown.

8, is a pivot pin or pintle by which. the hammer 5 and bracket 7 are pivotally connected together.

9, is a ratchet sector secured to the bracket 7, in concentric relation to the axis of the pivot pin 8, and in its preferred form the said sector is provided with ratchet teeth or depressions 10, on its opposite sides, as shown more particularly in Fig. 3.

11, is a coiled spring encircling the pintle 8 so as to have a pivotal arrangement thereon; such spring is provided with extension members 12, adapted for engagement in orifices formed therefor in the hammer 5, and with a loop shaped member 13 arranged astride of the sector 9, and adapted for holding engagement in the ratchet teeth or depressions 10, to hold said member at its required adjustment in relation to said sector, and so that the tension of said spring can be changed and regulated as required, with a corresponding change or regulation of the frequency of vibrations of the hammer 5.

14, is a handle attached to the free end of the loop shaped member aforesaid, for the convenient manual manipulation of the same by the operator.

15, is a curved spring resting by its free ends upon. the yoke piece 3, and prevented from a turning movement thereon by depending ears 16, engaging the sides of the yoke piece shown. Such. spring is also provided with a central orifice for the passage of the adjusting screw a, aforesaid, and with a series ol corrugations 17 surrounding said orifice and adapted for yielding engagement with corresponding corrugations on the underside of the head of the adjustable screw i, as shown, in order that some force will be required to eilect a turning adjust ment of said screw, and so that accidental turning thereof will be prevented.

Having thus fully described my said. invention what I claim as new and desire to secure by Letters Patent is 1. In a vibrator, the combination of a fixed anvil, an adjustable anvil, a hammer or interrupter arranged between the same and consisting of a plate of metal hinged to a fixed bracket, a coiled spring connected to said hammer, and means for adjusting the resiliency of said spring, substantially as set forth.

2. In a vibrator, the combination of a fixed anvil, an adjustable anvil, a hammer or interrupter arranged. between the same and consisting of a plate of metal hinged to a fixed bracket, a coiled spring connected to said hammer, and means for adjusting the resiliency of said spring, the same comprising a ratchet sector and a manually operated extension of the spring adapted for engagement with said sector, substantiall as set forth.

3. In a vibrator, the combination of a fixed anvil, an adjust-able anvil, a hammer or interrupter arranged between the same and consisting of plate of metal having pivot ears at one end, a fixed bracket having pivotal connection with said cars, a coiled spring encircling the pivot ot said hammer, and means for adjusting the resiliency of said spring, substantially as set l'orth.

-l. in a vibrator, the combination of a iixed anvil, an adjustable anvil, a hammer or interrupter arranged between the same and consisting of a plate of metal having pivot ears at one end, a lixed bracket having pivotal connection with said ears, a coiled spring encircling the pivot axis of said hammer, and means for adjusting the resiliency of said spring, the same comprising a ratchet sector and a manuall r operated extension of the spring adapted for engagement with said sector, substantiall i as set forth.

.5. In a vibrator, the combination of a coil core forming a 'lixed anvil, a lixe l bracket carrying an adjustable screw or anvil, a hammer or interrupter arrange l between the anvils and consisting of a plate ol metal hinged to a lixed bracket, a coiled spring connected to said hammer, and means for adjusting the resiliency of said spring, substantially as set forth.

6. in a vibrator, the combination of a coil core forming a lixed anvil, a fixed bracket carrying an adjustable screw or anvil, a

hammer or interrupter a ranged between the anvils and consisting ol a plate ol metal hinged to a iixed bracket, a coiled spring connected to said hammer, and means for adjusting the resiliency of said spring, the same comprising a ratchet sector and a manually operated extension of the spring adapt-ed for engagement with said sector, substantially as set forth.

7. In a vibrator, the combination of a coil core forming a fixed anvil, a iixed bracket carrying an adjustable screw or anvil, a hammer or interrupter arranged between the anvils and consisting of a plate of metal having pivot ears at one end, a fixed bracket having pivotal connection with said ears, a coiled spring encircling the pivot axis of said hammer, and means for adjusting the resilienc r of said spring sul'istantiall v as set forth.

8. in a vibrator, the combination of a coil core forming a lixed anvil, a 'lixed bracket carrying an adjustable screw or anvil, a hammer i r interrupter arranged between the anvils and consisting of a plate of metal having pivot cars at one end, a iixed bracket having pivotal connection with said ears, a coiled spring encircling the pivot axis of said spring, and means for adjusting the resilienc of said spring, the same comprising a ratchet sector and a manuallv operated extension ol the spring adapted for engagement with said sector, substantially as set forth.

9. in a vibrator, the combination of a lixed anvil, a iixed bracket carrying a. headed adjustable screw or anvil, a hammer or interrupter arranged between said anvils, and a curved spring arranged on the bracket and beneath the head of said adjustable screw, the contact surl'aces oi said head and spring being formed with corrugations, substantiallv as st lortli.
